Below are pics of the plants that are growing everywhere in the mulch. Normally I would say they came in the mulch but the mulch is 2 years old so it has to be something new dropping and growing. Unfortunately they are REALLY slow growers. They have only produced a couple true leaves in the last 4 weeks. Does anyone have an idea on what they are and how to stop them from growing. I hate to use Round Up but there are so many and they keep on coming once they are pulled...HELP!
Thanks in advance for any advice
